To date, no randomised controlled trial has examined the effect of milk consumption on either iodine or selenium status. The possibility of increasing iodine and selenium intake by increasing milk consumption, a widely available and consumed foodstuff, in a population group vulnerable to micronutrient deficiency should be investigated. This would add valuable data to the knowledge base for iodine, where there is ongoing debate over the most appropriate means of increasing iodine intake amongst women of childbearing age in the UK where salt iodisation, the key strategy in preventing deficiency, is not implemented.
